I think there are two dimensions:
1) Allowing annotation properties to have subproperties so, e.g. that
skos:prefLabel and skos:altLabel can be subproperties of rdfs:label.
Mostly this is addressed by punning in 1.1 but there are still
annotation property leftovers like rdfs:label and rdfs:comment or any
other property where one doesn't want to make a commitment as to
whether they are datatype or object.
2) Some sort of easy tagging mechanism for labels - perhaps something
along the lines of the language tags. The case is that one ontology
is used by a variety of communities (proteomics, flow cytometry,
enzymology) each of which has preferred labels for some of the terms,
and it would be nice to have some global switch to select which view
you wanted to see.
btw, couldn't easily tell from the 1.1 spec whether one can add
annotations to labels (like this tag thing).

This is exactly the point I've been making for over a year now
regarding use of SKOS in biomedical ontology development, and it
is why we use SKOS:prefLabel for all classes in BIRNLex (as well
as having the redundant rdfs:label for interoperability
purposes). The "altLabel" provides a means not only to associate
lexical variants but ultimately to create "namespace qualified"
term sets or "views" of a single ontology with the terms tailored
to the needs of a specific community. There would need to be an
expansion of annotation support in OWL to fully implement this,
but SKOS can provide a means to standard that method in the
lexical domain, once the required annotation capabilities have
been added to OWL.

Would you mind explaining exactly what you need from the annotation
capabilities? We have been discussing a fairly clean way to beef up
OWL 1.1 annotations and I'd be curious to know if it handled this
(important) case.
